+C library for accessing the PostgreSQL parser outside of the server.
+
+This library uses the actual PostgreSQL server source to parse SQL queries and return the internal PostgreSQL parse tree.
+
+Note that this is mostly intended as a base library for pg_query (Ruby), pg_query.go (Go), pgsql-parser (Node), psqlparse (Python) and pglast (Python 3).
+
+You can find further background to why a query's parse tree is useful here: https://pganalyze.com/blog/parse-postgresql-queries-in-ruby.html
